Described is a method that includes taking radio measurements of radio node signals observable at a mobile device; obtaining motion measurement data indicative of motion of the mobile device; determining, based on the motion measurement data, a motion state of the mobile device; and providing the radio measurements taken or information representative thereof and the motion state or information representative thereof. Described is also a method that includes obtaining radio measurements of radio node signals observable at a mobile device or information representative thereof obtaining a motion state of the mobile device, the motion state having been determined based on motion measurement data indicative of motion of the mobile device, or information representative thereof determining a position estimate of the mobile device at least based on at least some radio measurements or information representative thereof and the obtained motion state of the mobile device or the information representative thereof.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the plurality of radio measurements comprises a chronological series of radio measurements.
3. The method of claim 1, wherein the motion state is determined independently of the plurality of radio measurements.
4. The method of claim 1, wherein the determining of the motion state of the mobile device is based on a motion sensor of the mobile device, in particular an inertial sensor, e.g. a gyroscope or an accelerometer.
5. The method of claim 1, wherein the determining of the motion state of the mobile device comprises utilizing a step frequency and/or a vibrational frequency content.
6. The method of claim 1, wherein the motion state indicates at least one motion type chosen from a plurality of motion types, each motion type being associated with a specific degree of motion.
7. The method of claim 6, wherein the motion state indicates a combination of at least two motion types.
8. The method of claim 1, wherein the motion state indicates at least one motion type of the following motion types: -stationary; -slow motion; -fast motion; -walking; -running; -cycling; and/or -driving.
10. The method of claim 9, wherein the determining of a position estimate of the mobile device is performed by a positioning algorithm and the positioning algorithm takes into account the motion state of the mobile device.
11. The method of claim 10, wherein the at least one parameter (a) is a parameter of the positioning algorithm for determining the position estimate of the mobile device and (b) is determined based at least in part on the motion state of the mobile device.
13. The method of claim 10, wherein a degree of filtering, dampening, smoothing and/or averaging applied by the positioning algorithm for determining the position estimate of the mobile device is determined based at least in part on the motion state.
14. The method of claim 9, wherein the determining of a position estimate of the mobile device employs a filtering or smoothing algorithm.
18. A computer readable storage medium in which computer program code is stored, the computer program code, when executed by a processor, causing an apparatus to perform the method according to claim 1.
20. The method of claim 12, further comprising setting the at least one parameter utilized by the positioning algorithm for determining the position estimate of the mobile device to a respective third value, in case the motion state corresponds to a third motion type indicating more movement than the second motion type.
21. The method of claim 9, wherein the motion state indicates a probability that the mobile device is moving with one or more motion types of the plurality of motion types.
